v0.8-alpha

• Now uses Room for storing Matrix credentials. You may need to log back in.
• Supports sending longer messages by splitting them into multiple parts.

• Old icon got removed for some reason, it is back.
• Added option to enable debug log, which is currently not viewable. But it will be soon.
• Proper error handling; Client should die much less frequently.

v0.7-alpha

Changes

• Added an "On send" option, which determines what should happen if the message is sent (or not sent) successfully
  • Options are: None, Reply (message mentioning you), Thread (a new thread to your message), and Reaction (check underneath your message)
• Updated every dependencies, rewrote the gradle

Minor tweaks

• Added scroll support for small devices
• Room ID validation has been updated to increase compatibility

Note: Previous app signing key got lost. You may see conflicts during install.

Log Improvements

Note: This update changes the database schema. While the migration code has been tested and confirmed to be working, I cannot make guarantees. If you install this version and the app crashes immediately after UI shows up, the only way to get it working again is uninstalling and reinstalling. Sorry.

Changes:
Encryption enabled by default (Upon creating room, the bot will send RoomEncryptionEvent which makes all messages in that room to be encrypted. Originally, the only way to get encryption working was having the server enable encryption by default, which is why this feature got overlooked because my server has this enabled.)
Better log messages (You can tap on the log messages to view them in detail)

Major Update: Commands (Fixed)

New features: Commands

(This is the output of the command !help)
These are the currently available commands:
!close: Close a room in a messaging space. Useful if you received an OTP SMS.
!ping: Check if your phone service is running.
!reload: Reloads Matrix clients on your phone.
!say <Reply>: Sends a message as a reply in a SMS room. By default, you can exclude this to send SMS back.
!new <Phone number>: Create a new chatroom on Matrix that sends messages to the given phone number. You will be invited into that room.

(Yes, v0.4 has been previously posted then deleted. Further testing showed some major issues that resulted in unresponsive bot, and has now been fixed.)
